I discussed this problem recently with one of the upstart developers. Unfortunately we didn't get a fix in time for 11.04, but as I recall to properly fix this we require features in upstart planned for 11.10. > And even if the startup script order is fixed in all these cases, its > always possible that the LDAP (or whatever) server will be unreachable > when a particular machine is started, which presumably could result in > the same ORPHANing process happening for cron session....

Theoretically, this could easily be extended to the ORPHAN case, but I'd have to give this some more thought (eg: what if ORPHAN is justified, ie the user really does not exist). -- You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. https://bugs.launchpad.net/bugs/27520 Title: cron daemon starts before LDAP client, causing "ORPHAN" message for all LDAP-defined users -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
